Describe the issue

WTHIT tooltips are not displayed on barriers, regardless of gamemode. Did not find any option for it either.

Additional context

At least creative should show it... But in my opinion actually all gamemodes should, because they are shown on F3 after all.

Invisible blocks are blacklisted by default, you can remove them from .minecraft/config/waila/blacklist.json. You will also need to do that on the server's side if you play on server.
